Rails Scaffold And Automated Testing Lab

Based on today's lesson, you'll need to:

Create a New Application
- Hint: Use rails new be sure to use the --api flag
1 Blog Model with the following Fields
- Title -> String
- Body -> String
full crud API routes (index, show, create, update, destroy)
- Hint: Use rails g scaffold
test the api

When finished generating your app, use the following steps to run automated testing and make sure your code works:

Ensure your rails server is running on localhost:3000. It needs to be up and running for the tests to work.
In your work folder (this does not need to live inside your rails project), create a file called test_blogs.rb
Paste the following code into your test_blogs.rb file and save it:

# To run tests, run this file, make sure to have installed minitest
# gem install minitest
require 'minitest/autorun'
require 'faraday'
require 'json'

## Test Class
class TestBlogs < Minitest::Test

    def test_index()
        puts("TESTING THE GET ROUTE")
        r = Faraday.get("http://localhost:3000/blogs/")
        assert r.status == 200
    end
    
    def test_create()
        puts("TESTING THE POST ROUTE")
        response = Faraday.post "http://localhost:3000/blogs/" do |request|
            request.body = {"title": "Super Blog", "body": "fsdadfasdf"}.to_json
            request.headers['Content-Type'] = 'application/json'
        end
        assert JSON.parse(response.body)["title"] == "Super Blog"
    end
    
    def test_update()
        puts("TESTING THE PUT ROUTE")

        response = Faraday.post "http://localhost:3000/blogs/" do |request|
            request.body = {"title": "Super Blog", "body": "dfadfadafd"}.to_json
            request.headers['Content-Type'] = 'application/json'
        end

        body = JSON.parse(response.body)

        response = Faraday.put "http://localhost:3000/blogs/#{body['id']}" do |request|
            request.body = {"title": "Super Blog II", "body": 5}.to_json
            request.headers['Content-Type'] = 'application/json'
        end

        body = JSON.parse(response.body)

        assert body["title"] == "Super Blog II"
    end
    
    def test_delete()
        puts("TESTING THE DELETE ROUTE")
        response = Faraday.post "http://localhost:3000/blogs/" do |request|
            request.body = {"title": "Super Blog", "body": "dfsdfsdf"}.to_json
            request.headers['Content-Type'] = 'application/json'
        end

        body = JSON.parse(response.body)

        id = body['id']

        response = Faraday.delete("http://localhost:3000/blogs/#{id}")

        assert response.status == 204
    end
end

Run one time: gem install faraday minitest
- These only need to be installed one time. You don't need to gem install every time you run your tests in the future.
Run the tests: ruby test_blogs.rb
See if your app passes the tests:
- It should have 0 failures and 0 errors. If not, make sure your rails server is running and you have migrated your database.
Take a look through the automated tests to get a feel for what they are doing. Feel free to do some googling for minitest and automated testing ruby to learn more.

Homework submission:

This homework counts as extra credit. To submit the homework, send us a screenshot of your tests passing like this:

It should have 0 failures and 0 errors.
